Paper Abstract

Experimental observation of reverse wavelength self-sweeping effect is reported in a bidirectional ytterbium-doped fiber ring laser. The wavelength self-sweeping regime - that a spontaneous, periodical, stable - can be obtained by the dynamical induced grating formed in an active medium due to the spatial hole burning. In this work, the reverse self- sweeping effect operates, for the first time, to the best of our knowledge, in 1.037 μm wavelength region. Besides, the fiber laser can generate a self-pulse signal and reverse wavelength self-sweeping with an average rate of 0.38 nm/s in the largest coverage of 2.75 nm. The self-pulse signal that modulated by inter-mode beating can be observed and the microsecond pulse train envelopes are in the range of 116-128 kHz.
